Abstract

As the number of Internet of Things (IoT) devices increases, services expand and illegal hacking and infringement methods become more sophisticated, an effective solution for blockchain technology is required as a fundamental solution to security threats. In this paper, we develop the security module of an IoT device based on blockchain technology that blocks hacking and information infringement and forms a multi-security blockchain system between the IoT device and the user device and we develop a user application. We contribute to addressing the security threats faced by IoT application services by developing a new method. In particular, we present some schemes for the development of a multi-security certification system based on blockchain for IoT security.

Highlights

The role of blockchain in the fourth industrial revolution, which includes information communication technology (ICT) convergence, is becoming more important
Since the blockchain method shares all the data in the user device, when more than 50% of the users manipulate by collusion, a problem may arise of recognizing the manipulated data in all user devices
Internet of Things (IoT) devices can respond to various hacking threats when transmitting information, so we propose a system that includes an IoT device, a user device, user certification, and data encryption for providing a secure channel between IoT devices

Summary

Introduction

The role of blockchain in the fourth industrial revolution, which includes information communication technology (ICT) convergence, is becoming more important. As the fourth industrial revolution is characterized by hyper-connectivity and superintelligence, blockchain technology is helping to reliably interconnect people and things. Blockchains are helping to reduce transaction costs based on mutual transparency and reliability through ICT convergence [1,2,3]. The rapid growth of the Internet of Things (IoT) is creating new levels of connectivity and empowering platforms by connecting people and devices in new ways of creating value. A focus of modern technology development is open innovation through digital convergence. For effective open innovation concepts and for the realization of IoT, cumulative and advanced use of big data is necessary [6,7]
